It consists of thin plates such as materials, color steel plates, color aluminum, stainless steel plates, melamine decorative plates, and ABS resin plates.
The space surrounded by these is filled with urethane foam (foam insulation) 105.

Next, the outer surface of the breaker 103 is pressed (FIG. 13), and the breakers 103 are stacked in a plurality of stages as shown in FIG. 14 to improve the productivity.

A flows between the double-sided materials 102 while reacting and expanding (indicated by arrows in FIG. 10). When the urethane stock solution 105A flows between the double-sided materials 102, 102, frictional resistance is generated between the urethane stock solution 105A and the double-sided materials 102, 102.
02 delays in the flow of the contact portion.

なる。When a delay occurs in the urethane stock solution 105A flowing between the double-sided materials 102, 102, an intermediate portion thereof advances before the face materials 102, 102 side, and the tip of the expanding urethane stock solution 105A collapses. Therefore, as shown in FIG. 11, the urethane stock solution 105A on the side of the face material 102,
A foaming gas, air, or the like is trapped between the collapsed urethane stock solution 105A. That is, the heat insulating structure 101
The urethane foam 105 solidifies in a state where air is entrained inside the double-sided materials 102, 102.

An air pocket 106 called a void is generated inside the space (FIG. 12). When the air pocket 106 is generated inside the face material 102, the urethane foam 105 does not exist in that portion, so the thin face material 102 is recessed only in the air pool 106. As a result, there is a problem that the appearance of the product is poor.

In the above publication, a pipe having countless fine air vent holes formed between both surfaces is provided, and a pipe and an inlet of a urethane stock solution are provided to face each other. In addition, the air vent holes provided in the pipe improve the flow of the urethane stock solution, and allow the gas and air generated at the time of filling to be discharged.

At the corners of the face material opposite to the air vent holes provided in the pipe, air pockets displaced by the growth of the foamed heat insulating material are likely to occur. For this reason, the corners of the face material may not be filled with urethane foam.

The foaming jig 10 of the heat insulating structure 1 is provided with a filling device and a control device (not shown) for the urethane stock solution 5A. Then, the urethane stock solution 5 </ b> A is injected between the face materials 2 and 2 from an injection port (not shown) of the foaming jig 10. When the urethane undiluted solution 5A is injected between the face materials 2 and 2, the urethane undiluted solution 5A expands as described in the conventional example, and fills between the two side materials 2 and 2 while flowing from the injection port to the surroundings.

As a result, the urethane stock solution 5A in the intermediate portion between the double-sided materials 2 and 2 flows in such a manner as to advance, and grows to form the urethane foam 5.

When the tip of A collapses, air is entrained inside the lower face material 2, and the entrained air expands the urethane stock solution 5.
Due to the pressure of A, the sheet 4 passes through the sheet 4 and is pushed out of the two-sided members 2 and 2 from the air vent holes 2A formed in the two-sided members 2 and 2 (arrows in FIG. 5).

成することが可能となる（図６）。The air pushed out from the air vent holes 2A enters the air passages 11A, passes therethrough, and is discharged from the end to the outside of the surface presser 11. Thereby, the air entrained by the urethane undiluted solution 5A can be discharged to the outside, and the heat insulating structure 1 in which the air accumulation (indicated by 6 in FIG. 5) generated inside the face material 2 is reliably prevented is formed. (FIG. 6).

る。Since a plurality of minute air vent holes 2A are formed in the entire area of each of the surface materials 2, the air between the surface materials 2 and 2 entrained by the urethane stock solution 5A is urethane. Due to the growth of the foam 5, the foam 5 is smoothly pushed out from each air vent hole 2A. In this way, it is possible to reliably prevent the inconvenience of generating air pockets inside the face materials 2 and 2.
Urethane foam 5 can be uniformly filled.
